13.8V / 10A DC Regulator Circuit

13.8V 10A DC Regulator

This is a dc regulator circuit which will give output voltage of 13.8V with current output about 10A. The circuit use 4 pieces of power transistor 2N3055 to boost the electric current, to make the circuit capable to deliver 10A current output. It also use IC regulator 7812, change the IC type will give different output voltage value.

For 13.8VDC output voltage, you need the DC input voltage about 18VDC at least. Don’t forget to mount the heatsink on the power transistor and give good trace/cabling/wiring to the circuit especially for grounding connection.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

    ВОПРОС: При заряде АБ были перепутаны провода (+ и -). Появившийся запах указал на неправильное подключение. Результат: U вых. увеличилось, и стало порядка 18 V. Что вышло из строя? Спасибо.
